对不起,我只是找到了.这里是:

您需要将Social.framework添加到项目中.将以下#import"Social/Social.h"添加到您的文件中

您可以创建3种类型的服务:

SLServiceTypeTwitter
SLServiceTypeFacebook
SLServiceTypeSinaWeibo

Facebook的例子.

SLComposeViewController *fbController = 
     [SLComposeViewController 
                 composeViewControllerForServiceType:SLServiceTypeFacebook];


if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
{
    SLComposeViewControllerCompletionHandler __block completionHandler=
    ^(SLComposeViewControllerResult result){

       [fbController dismissViewControllerAnimated:YES completion:nil];

       switch(result){
       case SLComposeViewControllerResultCancelled:
       default:
       {
           NSLog(@"Cancelled.....");

       }
           break;
       case SLComposeViewControllerResultDone:
       {
           NSLog(@"Posted....");
           UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"Sent" 
              message:nil
              delegate:nil 
              cancelButtonTitle:@"Dismiss" 
              otherButtonTitles: nil];
           [alert show];
       }
           break;
   }};

   [fbController addImage:[UIImage imageNamed:@"your_image.jpg"]];
   [fbController setInitialText:@"The initial text you want to send"];
   [fbController addURL:[NSURL URLWithString:@"the url you wanna share"]];
   [fbController setCompletionHandler:completionHandler];
   [self presentViewController:fbController animated:YES completion:nil];
}

希望这个对你有帮助.如果您想要其他社交网络,请更改SLServiceTypeFacebook以获取其他任何社交网络.
